TQ all whom t may concern:

Be it lrnown Ythat I, Diisnnfi BAUDnwYNs, a subject of the King of Belgium, residing at h/lontigniessur-Sambre, Belgium, have invented new and useful Improvements in and Relating to Flat Hoisting-Cables; and l do hereby declare the follow'ng to be a full, clear, and exact description of the same.

rlhe object of my present invention is to provide a flat hoisting cable by means of wires or l,textile materials or both and wherein two or more ropes each of which is formed of at least six strands or sections are arranged side by side and connected together by means of one or more flat wires or threads, inserted through the ropes so that the two central strands of each rope are embraced by said connecting wires, while the outer strands on opposite sides of the cable are not embraced by said wires. The purpose of this particular method of manufacturing cables is to produce cables of larger thickness and balance the load by an adequate winding of the cable.

My invention is illustrated in the accompanying drawings, wherein- Figure l is a fragmentary front elevation of the cable; Fig. 2 is an edge view of same, and Fig. 3 is a cross-section of same.

My cable made of metal or textile material is composed of two or more ropes a, each of which is formed of at least six strands, 7)'. Each rope is made with or without inner core al of hemp or other textile material. Each strand. of each rope is composed of more than two threads or wires c with or without core of hemp. The ropes of the cable are alternately twisted to the right and the left and arranged side by side so as to obtain the desired width of the cable. The strands may be twisted in the same direction as the ropes or in opposite directions, even if metal and .textile materials are used in mixture.

The ropes are connected together by means of one or more flat or semi-fiat threads or wires, CZ, having rounded rims or edges and which are inserted through the ropes so that the two central strands of each rope are embraced by the wires (Fig. 3) while the two outer strands on each face of the cable are outside the connecting wires.

As shown in the drawing the connecting wires maybe wound several times around the strands of each rope, so that a plurality of connecting wires may be superposed in the plane of the cross-section of the cable.

It is manifest that my cables may be manufactured of any number of wires, strands and ropes of any type, diameter and material. The connection of the ropes may also be produced by means of any number of wires or threads of any suitable material.

The particular connection of the ropes as herein described insures the thickness of the cable remaining constant.

Having now particularly described the nature of my sai-d invention and in what manner the same is to be performed, l de- Clare that what I claim and desire to secure by Letters Patent is l. A flat metal or textile hoisting cable, composed of two or more ropes, each of which is formed of at least six strands formed of more than two threads or wires, said ropes being arranged side by side and connected by means of one or more fiat cords or wires with rounded edges, inserted through the ropes so that the two central strands thereof are embraced by the cords or wires, while the remaining strands are outside the latter' substantially as and for the purpose set forth.

2. A flat flexible cable comprising a plurality of twisted ropes, each composed of a plurality of twisted strands, bands uniting the central strands of all the ropes formn ing a flat cable, the exterior strands of said ropes remaining free and forming the working surfaces of said cable.

3. A fiat cable, comprising a plurality of ropes side by side, said ropes being composed of a plurality of strands, and having the central strands of one rope mechanically united by separatc and independent bands to those of another rope, forming a pliable cable.

ln testimony whereof, l have signed my name to this specification in the presence of two subscribing witnesses.
